Weeds in agricultural system are becoming problem nowadays in which itreduces yield of many crops. Synthetic herbicides are usually used to controlweed growth. Meanwhile, using herbicides creates hazardous impacts onagricultural products and also increases environmental pollution. Thus, this studyaimed to evaluate the allelopahatic potential of Castor plant (fresh leaves, dryleaves, seeds) aqueous extracts on germination rate, germination value indicesand root growth on selected crop species. The inhibitory effects ofallelochemicals might be used against weeds as a controlling tool for decreasingweed emergence in field conditions. The study consists of 4 treatments replicated5 times within 7 days. Germination rate, germination value indices and rootlength were collected in the 7th day of the experiment. Data gathered wereanalyzed using one way ANOVA and tukey HSD for comparison. Based on theresults, it shows that fresh leaves and seed aqueous extract had an allopathiceffect on the seed germination and germination value of Zea mays L. andSolanum lycopersicum. In terms of root length inhibition, all treatments had aninhibition effect on the selected crop species. The result showed great potentialfor the natural herbicide from the determined parts of identified plant
